On the first day of the second series of interleague games, Major League Baseball hit it out of the park, averaging 34,881 per game while seeing ballparks filled to 80% of capacity. The average per game across the league was a 6 percent increase from the same Friday of interleague last year when ballparks pulled in an average of 32,905.

On the sellout front, it shouldn't be surprising that the Cubs sold out Wrigley Field with the Yankees in town, but the biggest benefactor was the Athletics who had the cross Bay rivals in the World Champion San Francisco Giants at Overstock.com Stadium. It was just the third sellout of the season for the A's. The other two? Opening Day, and May 30th when they hosted the Yankees.

Still, how does it stack up to intraleague play? Friday in the majors ranked as the third best day by percentage of ballparks filled behind only Opening Day and last Saturday.

The real key will be how interleague fares when it moves off the weekend and into the weekdays. For that, look to reports each day throughout the coming week.

Here is a breakdown of the numbers, along with the promotions, many of which were fireworks displays.
